To all whom t may concern.' I

Be it known that I, @Ln/'ER CRoscY, a c1t1'y zen ot the United States, residing at Paul7 `Ramsey county, Minnesota, have 1nrented new and uset'ul lmprovements in Clips tor 'Vire-Rope Members, of which the following is a specication.

Mv invention relates to improvements in wire, am wire rope, structures, its object being to produce an improved form of submarine net especially of the type designed and adapted :tor the protection of harbors and ship channels against submarine vessels..

rhe essential feature of my invention is a clip or clamp for interconnecting the wire or rope members of the net at their intersections. ln a structure of this character it is essential that the members shall cross each other at exactly right angles, and be held interconnected with absolute rigidity in order that as the net is suspended in the water it will ali'ord the most stanch and rigid resi. "ance to the impact of a submerged vessel, without distortion of the structure or slipping of the members upon each other.

To this end my invention consists essentially in a clamp having a body, preferably of forged steel, and elliptical in general contour, having formed in its tace a transverse semi-cylindrical groove adapted to receive and hold one wire rope member, and having arranged on opposite sides of said groove studs with parallel faces at right angles to said groove, and interspaced the thickness of, and adapted to receive, the other wire rope member superimposed transversely up on the irst. At the ends of the clamp body are bolt holes adapted to receive a U-shaped bolt straddling the crossed net members, and adapted to be secured in place by suitable nuts.

In the accompanying drawings, forming part of this specification,

Figure l is a plan view of one of my improved clamps applied to wire ropes as distinguished from individual wires, showing the manner in which the rope members of the net are engaged and held thereby;

Fig. 2 is a reverse, plan view ot the same showing the securing` nuts, and the ropes in broken lines;

Fig. 3 is a plan view of the body of the rclamp, the U-b'olt and ropes being removed therefrom i F ig. t is an end elevation of the same; and

Fig is aview of my improved net. v ln the drawings A represents the body of the clamp, as a block of forged steel, substantially elliptical in form and having near each end bolt holes 2 to receive the threaded ends or" the U-bolt 3, )rovided with securing nuts et. he clamp body is provided with a semi-cylindrical groove 5, running at an oblique angle transversely ot the same, between the boit holes 2 and serving as a bed or seat for the bottom rope member 6. Disposed on opposite sides of the groove and with their faces at right angles thereto, are studs 7 adapted to receive and hold in place between them the second superposed rope member 8. The members are then secured rigidly in these respective positions by the U-bolt 3 straddling them at their intersection and passing through the clamp body and engaged by the nuts 4.

l't will thus be seen that the under member is held by means of the walls 9 and 10 of the groove 5 in its transverse position upon the block, while the member 8 is similarly held by the studs 7 which project above the under member and stand at right angles to its bed or seat. The U-bolt, as secured by its nuts, prevents any disengagement or loosening ot the under member from its seat, or of the upper member from its place upon the other. The net structure being thus intersecured at each interconnection of its members, it is impossible of distortion, the members being held rigidly at right angles with each other.

Vhile my invention is adapted primarily for the construction of submarine nets, it is obvious that it may be used for other purposes and inother relations in the Jforming of nets with rectilinear meshes but not necessarily rectangular meshes.

lflaving thus described my invention, what l claim and desire to secure by Letters Patent is:

l. In a structure of the class described, a clamp for the members thereof comprising a body having means upon its face for engaging and holding superposed net members at right angles to each other consisting of Abed or body having a transverse semi-cylindrical groove adapted to receive a Wire or rope member, and studs arranged on opposite sides of said groove withxtheir faces at right angles thereto, and a U-bolt engaging perforations in said clamp body and :stradlling the included net members.

3. A clamp for crossed Wire ropes7 oomprising a body having a groove engaging one rope and -opposite stiids'engaging the superposed rope and holding said ropesat the desired angle, and aU-shaped bolt straddling said ropes and extending through said body.

4. A clamp for crossed Wire ropes, comprising a. Vbleek having 'a groove in its' face adapted to engage one rope member, studs on opposite sides of' said groove adapted to engage vthe other superposed rope member and determine the angle between said mem hers and a U-shaped bolt straddling said members and secured to said bleek.
